Notes. Fluxes and masses are shown for three datasets at resolutions indicated in the header. The first row corresponds to an elliptical aperture encompassing the entire NGC 2770, whereas the following two rows correspond to rectangle apertures encompassing the north-western and south-eastern halves. The fourth and fifth columns correspond to the projected distance from NGC 2770.
